Bug ID: 23485
Summary: info variables: Types of static variables of the same
name get mangled together
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org

FAIL: gdb-8.1-25.fc28.x86_64
FAIL: 3fbbcf473a59df74a0b5d9ee343169f778fbd054

I have it reproducible only on Fedora 28 glibc-debuginfo.

glibc-2.27-30.fc28.x86_64
gdb-8.1-25.fc28.x86_64
gdb -batch /lib64/libc.so.6 -ex 'info variables'|grep -4 -w null

Actual:
File vfprintf.c:
static const wchar_t null[7];

Expected:
File vfprintf.c:
static const char null[7];
File vfwprintf.c:
static const wchar_t null[7];

.gdb_index is not present (that is some unrelated bug).
